DISTRIBUTING-VALVE FOR ACETYLENE-TANKS.

Patented Aug. 12,1913.

Application filed September 9, 1912. Serial No. 719,488.

To all whom it may concern:

Be it known that I, LARS L. 01E, a subject of the King of Norway, havingdeclared my intention of becoming a citizen of the United States,residing at San Pedro, in the county of Los 'Angeles and State ofCalifornia, have invented a new and useful Distributing Valve forAcetylene Tanks, of which the following is a specification.

This invention relates to means for distributing acetylene gas to thelamps of a power vehicle, and also to the engines there of, and the mainobject of the invention is to provide means whereby the pressure of thesupply of gas to the lamps may be readily regulated without interferencewith the supply of gas for starting the engines.

Another object of the invent-ion is to provide means whereby the supplyof gas for the lamps may be regulated by a permanent or set regulationindependent of the shut-off valve, so that when the shut-ofi valve isopened, the rate of supply of gas to the lamps is determined by theregulating valve and said regulating valve does not have to be adjusted,each time the gas is turned onto the lamps.

Another object of the invention is to reduce to a minimum the number ofconnections or couplings required between the tank and the gas consumingdevice, thereby minimizing the leakage.

Other objects of the invention will appear hereinafter.

The accompanying drawings illustrate an embodiment of the invention, andreferring thereto:

Figure 1 is a diagrammatic elevation, showing the application of thedistributing means. Fig. 2 is a side elevation of the distributingvalve. Fig. 3 is a vertical section thereof. Fig. 4 is a sect-ion online m m in Fig. 2.

The valve comprises a casing 1, preferably L-shaped, having two arms orportions 2 and 2 which may be substantially at right angles to oneanother. The casing portion 1 is formed with an interior bore 3 toreceive a valve stem 4, said valve stem having a screw threaded portion5, screwing in a screw threaded portion 6 of said bore and the inner endof said valve stem being formed with a tapering or conical shaped valveplug member 8 cooperating with a conical valve seat 9. From the end ofsaid conical valve seat, a reduced bore 10 extends inwardly tocommunicate with the inner end of a similar bore 11 which extendsinwardly from a coni cal valve seat 12 formed at the inner end of a bore13 in the other arm or portion 2 of the casing. A valve stem 14 extendsin said bore 13 and is provided at its inner end with a taper or conicalvalve portion 15 cooperating with said seat, and is further providedwith a screw threaded portion 15 engaging with a screw thread 17 in thebore 13. The outer ends of the bores 3 and 13 are formed with recessesor chamber 18 to receive packing material held in place by glands 20forming stuffing boxes for the respective valve stems. The outer ends ofthe valve stems 4 and 14 are formed with squared portions 21 and 22 toreceive wrenches for turning the valves to open or close the same. Thebase or central portion of the valve casing is formed with a boss 24provided with a bore 25 communicating with the bore 3 aforesaid, andwith a chamber or circular recess 26 surrounded by a circular flange 27,screw threaded as at 28 to receive a coupling ring 29 for a union member30. Said union member is formed with a shoulder 31 adapted to cooperatewith a flange 32 on said coupling ring and is formed with a taperingboss 34 adapted to cooperate with a tapering seat 35 in the casing 36for the main valve of the acetylene tank 38, said main valve having ascrew 37 to engage the coupling ring 29.

The lamp connection consists of a nipple 39, screwing into the valvebody or casing and having a bore 40 communicating through a channel 41in said valve body with the bore 13 for the valve stem 14, said valvestem being sufficiently smaller than the bore to enable passage of thegas around the valve stem to said nipple. Said nipple is adapted toreceive the tube 43 leading to the lamps, indicated at 44.

The starter connection consists of a nipple or tube 45 screwing into thevalve body 1 and having a bore 46 communicating with the bore 3. A pipe47 leads from nipple 45 to the engine indicated at 48, to supply gas tothe engine for starting the same.

The operation is as follows: lVhen the main valve 36 of the acetylenetank 38 is opened, the gas flows to the channel or bore 3 of the valvecasing 1 and the starter connection being in communication with thisbore, the gas under the full pressure as controlled by opening the mainvalve 36 passes to the starting connection so that gas under fullpressure is supplied for starting the engine. Assuming that the valve 4is closed, no gas passes at this time to the lamps, but when the valve 4is opened, gas passes from the bore 3 through the channels 10 and 11, tothe valve 1 1, and said valve having been previously set to give theproper regulation, the gas flows past this valve into bore 13 and outthrough the lamp connections 39 and 13 to the lamps, the pressuresupplied to the lamps being regulated by proper adjustment of the valve1st, and this valve being left in adjusted position when the shut-oilvalve 4 is closed, so that gas is supplied at the proper pressure forthe lamps at every operation without having to make any specialadjustment therefor.

By making the valve casing in one solid integral body, and making theconnections for the lamps and starter to said body without the use of aunion, I provide for the conncction from the tank to the said devices bythe use of a single union, thereby reducing to a minimum the leakage ofgas. In devices of this kind, itis usual to use three or four unions inthe connections, involving considerable leakage, as the unions areliable not to be gas tight. Only one union is necessary for uncouplingthe tank for recharging, and my invention, therefore, reduces the numberof unions as far as possible.

What I claim is:

1. A distributing valve for acetylene tanks, comprising a valve casinghaving an inlet opening for communicating with the outlet valve of theacetylene tank, a starter connection communicating with said inletopening, a lamp supply connection, a regulating valve working in saidcasing and controlling communication from said inlet opening to saidlamp supply connection, said valve being adjustable to regulate thepressure on the lamp supply connection, and a shut-off valve forshutting off communication from said opening to said regulating valve.

2. A distributing valve for acetylene tanks, comprising a valve casingformed as a solid integral body, having an inlet opening forcommunicating with the out-let valve of the acetylene tank, a starterconnection communicating with said inlet opening, a lamp supplyconnection, a regulating valve working in said casing and controllingcommunication from said inlet opening to said lamp supply connection,said valve being adjustable to regulate the pressure on the lamp supplyconnection, and a shut-oil valve for shutting off communication fromsaid opening to said regulating valve, said starter and lamp connectionsbeing provided with screw means screwing directly into said body and thesaid inlet opening being provided with a union for connection to thevalve of the acetylene tank.

In testimony whereof, I have hereunto set my hand at Los Angeles,California this 30th day of August, 1912.
